Ayoung woman sees her doctor with complaints that the bones in her left knee regularly dislocate, or move out of their usual place, painfully. which of the following is the most likely conclusion to be drawn from this?
her knee joint's synovial fluid is not an effective lubricant between her bones.
her bones have become perforated and brittle due to lack of calcium in her diet.
her cartilage has deteriorated, providing less cushioning and causing her pain.
her knee ligaments are weakened or injured so they can't stabilize the bones

Option D, Her knee ligaments are weakened or injured so they can't stabilize the bones

Explanation:

Ligaments act as a strong bands of body tissue whose main function is to provide connection between two bones or cartilages. It also supports bones and cartilages.

One of its major function is to provide strength and support to a joint so that it do not move too far from its line and get dislocated.

Here, the young woman has knee dislocation issue and since supporting a joint is the function of ligand , it is sure that some problems are there with the ligand

Hence, option D is correct

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
